You are right, I have introduced this when I was working on improving tests :(

>                 Key: WW-5028
>                 URL:
>             Project: Struts 2
>          Issue Type: Bug
>          Components: Dispatch Filter
>    Affects Versions: 2.5.18
>            Reporter: Stuart Harper
>            Priority: Minor
>             Fix For: 2.5.21, 2.6
> After upgrading from Struts 2.3.x to 2.5.x we noticed a stack trace in our logs which
was not previously present. The error is actually quite minor and doesn't impact any functionality,
the problem is we have no ability to control its presence in our logs do the way the
prints directly to the console.
> This can be seen in class org.apache.struts2.dispatcher.Dispatcher around line 586
> Only after the error is printed is a check made on whether to handle it. The exception
is then rethrown.
> I think it would make more sense to use the logging framework to log exceptions or otherwise
give us some control over whether this appears. As it is it's impossible to turn it off.
